End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

I got an eMail notification about an upcoming update for Thunderbird snap/flatpak configs, but I don't see any entry for Thunderbird in my "~/.var/app/" directory. There is an entry for Firefox, but nothing for Thunderbird. Yet Thunderbird still updates regularly and successfully.

What should I do, in order to conform to the eMail notification instructions?

Running the command "snap info thunderbird" returns the following --

name: thunderbird summary: Mozilla Thunderbird email application publisher: Canonical✓ store-url: https://snapcraft.io/thunderbird contact: https://www.thunderbird.net/contact/ license: unset description: |

 **ANNOUNCEMENT:** The snap channels are changing. Action is required by July 21, 2026
 to stay on ESR.
